JEWELRY
Jewelry is also better bought used than new. Before buying off Craigslist or from a private seller, however, be sure to get an appraisal, particularly if a significant amount of money is involved.
You can also find quality used baubles by shopping for estate jewelry from jewelers or reputable pawn shops. If you want to buy online, eBay may be a good way to go so long as you keep your eyes open for scams and use a safe payment method. (No wire transfers, people.)
